BACKGROUND 1. Field

The present invention relates to a display device and a method thereof,and more particularly to a display device and a method thereof, whichcan adjust functions of the display device.

2. Description of the Related Art

A display device in the related art, such as a television (TV) or amonitor, is provided with a plurality of input buttons for performing ascreen state adjustment, a volume adjustment, a channel adjustment, anda power on/off adjustment. Such input buttons are arranged at a lowerend of a front surface of a screen so that a user can easily operate thebuttons, but may also be arranged at a location which is not exposed toan outside (e.g., a side surface or a rear surface of the displaydevice) in accordance with a change of design or miniaturization of thedisplay device.

As the plurality of input buttons for adjusting the functions of thedisplay device are arranged on the side surface or the rear surface ofthe display device, a user must accept inconvenience in finding an inputbutton for adjusting a desired function among the plurality of inputbuttons. Particularly, with the recent development of a display devicehaving diverse functions such as a smart TV, the number of input buttonsfor operating the display device has been increased, and thus the usermust put much more time in finding the input button for adjusting thedesired function, which causes a greater inconvenience in use.

On the other hand, in the related art, a function guide informationwindow that is related to the plurality of input buttons is provided onthe screen of a display device through sensing of a user's hand when theuser's hand approaches a location where the plurality of input buttonsare positioned. Accordingly, the user can confirm a location of adesired input button is positioned with reference to the function guideinformation window displayed on the screen. Nevertheless, since the useris unable to confirm the location of the plurality of input buttonsdirectly in plain sight (i.e., since the buttons are out of view of theuser), the user is limited in finding a desired input button withreference to the function guide information window displayed on thescreen, and it causes great inconvenience for the user to operate theinput button while viewing the function guide information window. Inaddition, since information that is provided on the function guideinformation window through the sensing of the user's hand using a sensordoes not correspond to the operation of the input button that the useractually intends to operate, it becomes very difficult for the user tooperate the desired function.

In an exemplary embodiment, if one of theother adjustment menus of the display device is a screen adjustmentmenu, the second UI may include the center area (a) related to the entermenu and an area (d) related to the screen adjustment. In anotherexemplary embodiment, the second UI may be a circular UI that includestwo areas arranged in upper and lower directions and a center area.Here, the upper area of the two areas includes one of the menus relatedto one of the other function adjustments of the display device. Further,the lower area includes one of the remaining menus except for the menuincluded in the upper area among the other menus related to the functionadjustments of the display device. Further, the center area includes theenter menu.

FIG. 6 is an exemplary diagram illustrating a UI related to integratedadjustment that is displayed on the screen of a display device accordingto another exemplary embodiment.

As illustrated, if the moving operation or the push operation of the jogswitch 110 is performed in at least one of the upper, lower, left, andright directions the UI execution unit 121 executes an integrated UIcapable of performing adjustments of the channel, volume, and otherfunctions of the display device such that the integrate UI is displayed.The integrated UI that is displayed on the screen in accordance with theintegrated UI execution command of the UI execution unit 121 may be acircular UI 610 that includes four areas arranged in upper, lower, left,and right directions and a center area. Here, the center area includesan enter menu (a) for executing the channel, volume, and other functionsof the display device, performing a changeover operation to the previousstage, or finishing the execution of the circular UI 610 so that thecircular UI 610 is no longer displayed. Further, the four areas arrangedin the upper, lower, left, and right directions include different menusin accordance with the user's setting. According to the exemplaryembodiments, among the four areas, the upper area (b) includes a submenu related to a smart hub adjustment, and the lower area (c) includesa menu related to power off. Further, the left area (d) includes asetting menu related to the channel, volume, and screen adjustments, andthe right area (e) includes a source menu related to an external inputadjustment for controlling an external device.

On the other hand, as described above, the display unit 130, whichdisplays the first UI for adjusting the channel or volume of the displaydevice and the second UI for adjusting other functions of the displaydevice in accordance with the operation contents of the jog switch 110,can display an enter menu function guide UI in accordance with a pushoperation time of the jog switch 110 (e.g., a length of time the jogswitch 110 is held in the pushed position) that occurs in the presenceof the first or second UI, and is displayed together with the first orsecond UI. Such an enter menu function guide UI will be describedthrough FIG. 7.

FIG. 7 is an exemplary diagram illustrating an enter menu function guideUI that is displayed on the screen of a display device according toanother exemplary embodiment of the present invention.

As described above, the enter menu function guide UI that is displayedon the screen together with the first or second UI is a UI for guidingthe enter function in accordance with the push operation time of the jogswitch 110. In an exemplary embodiment, if the jog switch 110 isoperated for a short time as shown as “A”, the user can perform theadjustment of the menu that the user intends to adjust. By contrast, ifthe jog switch 110 is operated for a long time as shown as “B”, the usercan perform a changeover operation of the menu to transition the menufrom the current menu stage to a previous menu stage. On the other hand,if the jog switch 110 is operated for a long time in a state where thecurrent menu stage is the uppermost stage among different menu stages,the execution of the first or second UI that is currently displayed onthe screen is finished such that the first or second UI is no longerdisplayed. Accordingly, the first or second UI that is displayed on thescreen disappears from the screen.

As described above, if the moving operation or the push operation of thejog switch 110 is performed in a state where the first or second UI isexecuted in accordance with the execution command from the UI executionunit 121, the UI processing unit 122 adjusts the channel or volumerelated to the first UI or other functions of the display device relatedto the second UI in response to the moving operation or the pushoperation of the jog switch 110. The UI processing unit 122 can beachieved through the first UI adjustment unit 123 and the first UI menuemphasis unit 124.

The first UI adjustment unit 123 adjusts the channel or volume inaccordance with the moving operation of the jog switch 110 in a statewhere the first UI is executed. The first UI adjustment unit 123finishes the execution of the first UI in accordance with the pushoperation of the jog switch 110 for a preset time in a state where thefirst UI is executed. The first UI menu emphasis unit 124 generates ahighlight mark in a menu area related to the channel or volume that isadjusted by the first UI adjustment unit. In an exemplary embodiment, asillustrated in FIG. 3, if the moving operation of the jog switch 110 isperformed in the upper side direction in a state where the first UI isexecuted, the first UI menu emphasis unit 124 generates a highlight markso that the area related to the channel adjustment is emphasized.

Thereafter, if the push operation of the jog switch 110 is performedwithin a preset time of highlighting an area, the first UI adjustmentunit 123 performs a process corresponding to the highlighted area sothat the channel-up adjustment is adjusted. Accordingly, if the movingoperation of the jog switch 110 is performed in the upper side directionand then the enter function command is received, the first UI adjustmentunit 123 processes the channel-up command. Alternatively, the channel upadjustment may be performed without receiving the enter functioncommand.

On the other hand, if the push operation of the jog switch 110 isperformed for a time that exceeds the preset time of highlighting theselected area, the first UI adjustment unit 123 performs a changeover toa first UI state that is initially displayed on the screen. That is, thehighlighting disappears from the first UI and the first UI returns toits original state. Thereafter, if another push operation of the jogswitch 110 is performed for a time that exceeds the preset time, thefirst UI adjustment unit 123 finishes the execution of the first UI thatis currently displayed on the screen such that the first UI is no longerdisplayed.

In another exemplary embodiment, as illustrated in FIG. 4, if the jogswitch 110 is operated in the upper or lower side direction in a statewhere the first UI is executed, the first UI adjustment unit 123 adjuststhe channel-up or channel-down in response to the operation in the upperor lower side direction. On the other hand, if the jog switch 110 isoperated in the left or right side direction in a state where the firstUI is executed, the first UI adjustment unit 123 adjusts the volume-upor volume-down in response to the operation in the left or right sidedirection. On the other hand, if the push operation of the jog switch110 is performed in a state where the first UI is executed, the first UIadjustment unit 123 finishes the execution of the first UI that iscurrently displayed on the screen.

As described above, the UI processing unit 122 that adjusts the channelor volume related to the first UI can adjust other functions of thedisplay device related to the second UI through the second UI menuemphasis unit 125 and the second UI emphasis unit 126. The second UImenu emphasis unit 126 generates a highlight mark so that the menu areathat corresponds to the moving operation direction of the jog switch 110among the plurality of menus related to the second UI is emphasized in astate where the second UI is executed. Further, the second UI adjustmentunit 126 adjusts the function related to the highlighted menu inaccordance with the push operation and the moving operation of the jogswitch 110 in a state where the highlight is processed in the menu area.As described above, if the push operation of the jog switch 110 isperformed for the preset time in a state where the second UI isexecuted, the second UI adjustment unit 126 performs a changeoveroperation from the currently proceeding menu stage to the previous menustage or finishes the execution of the second UI that is currentlydisplayed.

In the exemplary embodiment, if the jog switch 110 is operated in theleft side direction in a state where the second UI that is a circular UIis executed, the second UI menu emphasis unit 125 generates a highlightmark so that the area that includes the adjustment menu related to thescreen adjustment is emphasized.

If the operation of the jog switch 110 is performed in a state where amenu area from among a plurality of menu areas related to the second UIis highlighted, the second UI menu emphasis unit 125 may move thehighlight to a menu area corresponding to a moving direction of the jogswitch 110.

If the push operation of the jog switch 110 is performed for less than apreset threshold time in a state where a menu area from among aplurality of menus related to the second UI is highlighted, the secondUI adjustment unit 126 outputs a menu window regarding thehighlight-processed menu. As shown in FIG. 5, if the push operation isperformed on an area including the adjustment menu related to the screenadjustment for less than a preset threshold time, the second UIadjustment unit 126 outputs a menu window of the menu related to thescreen adjustment.

Thereafter, if the push operation of the jog switch 110 is performedwithin the preset time, the second adjustment unit 126 outputs asub-menu window of the adjustment menu related to the screen adjustment.If the moving operation and the push operation of the jog switch 110 areperformed in a state where the sub-menu window is output and displayed,the second UI adjustment unit 126 can adjusts the color, brightness, orsize of the screen in response to the operation of the jog switch 110.On the other hand, if the push operation of the jog switch 110 isperformed for a time that exceeds the preset threshold time in any stageof the above-described stages, the second UI adjustment unit 126performs a changeover operation of the menu to transition the menu fromthe current menu stage to the previous menu stage.

At this time, if the current stage is the initial screen display stage,the second UI adjustment unit 126 finishes the execution of the secondUI that is currently displayed on the screen such that the second UI isno longer displayed.

On the other hand, if the moving operation or the push operation of thejog switch 110 is not performed for the preset time in a state where thefirst or second UI is executed through the UI execution unit 121, thefirst UI adjustment unit 124 and the second UI adjustment unit 126finishes the execution of the first UI or the second UI that iscurrently displayed on the screen. That is, the first UI adjustment unit124 and the second UI adjustment unit 126 check whether the jog switch110 is operated for the preset time in a state where the first or secondUI is executed. If it is determined that the jog switch 110 is notoperated for the preset time, the execution of the first or second UIthat is currently displayed on the screen is automatically finished andremoved from the display.

Up to now, the respective constituent elements of the display devicehave been described in detail. Hereinafter, a method of adjustingfunctions of the display device in accordance with the operation of thejog switch according to an exemplary embodiment will be described.

FIG. 8 is a flowchart illustrating a method of adjusting functions of adisplay device according to an exemplary embodiment.

As illustrated, the display device monitors and determines whether thejog switch is operated (S180). Here, the jog switch is an operationmeans for adjusting other functions of the display device such as thevolume, channel, and screen state. The jog switch can perform a movingoperation in the upper, lower, left, and right directions in the samemanner as the joystick and can perform a push operation in the samemanner as the input button. However, the exemplary embodiment is notlimited thereto, and the jog switch can perform a rotation operation inthe left and right directions. The jog switch is formed to project witha predetermined height from one side surface or one side of the rearsurface of the display device. Accordingly, a user can easily graspwhich point the jog switch is formed at through feeling in the user'shand only.

When it is determined that the jog switch is operated (S180), thedisplay device determines whether the operation of the jog switch is amoving operation in at least one of the upper, lower, left, and rightdirections or a push operation (S820). If it is determined that themoving operation of the jog switch is performed in at least one of theupper, lower, left, and right directions, the display device displaysthe first UI which enables the channel and volume adjustments on thescreen (S830).

On the other hand, the jog switch may perform a push operation relatedto a power on/off of the display device. Thus, if the push operation ofthe jog switch is performed in a state where the power of the displaydevice is off, the display device may turn on the power, at the sametime, display the first UI.

Here, the first UI may be displayed on the screen as illustrated in FIG.3 or 4. For example, as illustrated in FIG. 3, the first UI may be acircular UI that includes four areas arranged in the upper, lower, left,and right directions and a center area. Here, the center area includesan enter menu for finishing the execution of the circular UI or fordisplaying the previous state of the current UI on the screen. Further,among the four areas that are arranged in the upper, lower, left, andright directions, the upper area includes a channel-up menu, and thelower area includes a channel-down menu. Further, the left area includesa volume-down menu, and the right area includes a volume-up menu.However, the exemplary embodiment is not limited thereto, and thepositions of the menus that are included in the respective areas may beset differently.

Further, as illustrated in FIG. 4, the first UI may be displayed on thescreen as a bar graph type UI. The upper bar graph type UI may be a UIrelated to channel adjustment, and the lower bar graph type UI may be aUI related to volume adjustment. However, the exemplary embodiment isnot limited thereto, and the upper bar graph type UI may be a UI relatedto volume adjustment and the lower bar graph type UI may be a UI relatedto channel adjustment in accordance with the user's setting. Therespective bar graph type UIs may be vertically formed.

On the other hand, if it is determined that the push operation of thejog switch is performed, the display device displays the second UIrelated to other function adjustments of the display device on thescreen (S840).

According to an exemplary embodiment, as described above, if the pushoperation is performed on the center area of the jog switch in a statewhere the first UI is executed, the display device may convert the firstUI for adjusting a channel or a volume into the second UI for adjustingother functions of the display device.

Here, as illustrated in FIG. 5, the second UI may be a circular UI thatincludes four areas arranged in the upper, lower, left, and rightdirections and a center area, or a block type UI that includes a centerarea and four areas separately arranged in the upper, lower, left, andright directions from the center area. The center area of the second UIincludes an enter menu for finishing the execution of the second UI orfor displaying the previous state of the current UI on the screen.Further, the four areas arranged in the upper, lower, left, and rightdirections include different menus in accordance with the user'ssetting. As illustrated in FIG. 5, the upper area includes a sub menurelated to a smart hub adjustment, and the lower area includes a menurelated to power off. Further, the left area includes an adjustment menufor screen adjustment, and the right area includes a source menu relatedto an external input adjustment.

As described above, if a following operation of the jog switch isperformed in a state where the first UI related to the channel andvolume adjustments or the second UI related to other functionadjustments of the display device is displayed on the screen, thedisplay device adjusts the corresponding function of the first UI or thesecond UI in accordance with the following operation contents of the jogswitch (S850). In an exemplary embodiment, if the moving operation ofthe jog switch is performed upward or downward in a state where thefirst UI is displayed on the screen, the display device adjusts thechannel-up or channel-down. In another exemplary embodiment, if themoving operation of the jog switch is performed leftward or rightward ina state where the first UI is displayed on the screen, the displaydevice adjusts the volume-up or volume-down. In still another exemplaryembodiment, if the push operation of the jog switch is performed in astate where the first UI is displayed on the screen, the display devicefinishes the execution of the first UI. Accordingly, the first UI thatis displayed on the screen disappears from the screen.

On the other hand, in still another exemplary embodiment, if the movingoperation of the jog switch is performed in any one of the upper, lower,left, and right directions in a state where the second UI is executed,the display device generates a highlight mark so that the area thatcorresponds to the direction corresponding to the moving operation ofthe jog switch is emphasized. Thereafter, if the push operation of thejog switch is performed for a preset threshold time, that is, for ashort time, the menu in the highlighted area is adjusted. That is, thearea which displays the highlighted menu is adjusted to display asub-menu therein.

If an operation of the jog switch is performed in a state where thehighlight is processed in a menu area from among a plurality of menusrelated to the second UI, the display device may move the highlight tothe menu area corresponding to a moving direction of the operated jogswitch.

If the push operation of the jog switch is performed for less than apreset threshold time in a state where the highlight is processed in amenu area from among the plurality of menus related to the second UI,the display device adjusts the menu in the highlighted-area.

For example, if the push operation of the jog switch is performed for ashort time in a state where the left menu that includes the menu relatedto the screen adjustment is highlight-processed, the display deviceoutputs a sub-menu window of the menu area related to the screenadjustment on the screen. If the moving operation of the jog switch isperformed in a state where the sub-menu window is output, the displaydevice may adjust the color, brightness, or size of the screen. On theother hand, if the push operation of the jog switch is performed for atime that exceeds the preset threshold time in a state where the secondUI is executed, the display device performs a changeover operation totransition the menu from the current UI to the previous UI, or finishesthe execution of the second UI.

In still another exemplary embodiment, if it is determined that the jogswitch is not operated for the preset time in a state where the first orsecond UI is executed, the execution of the first or second UI that iscurrently displayed on the screen is automatically finished.

As described above, the user can easily adjust diverse functions of thedisplay device through the moving operation or the push operation of onejog switch that is formed on the rear surface or the side surface of thedisplay device according to the exemplary embodiments.
